Introduction

First, RTFM.

Have you read it? If you haven't go read it. Cuz I'll keep everything short.

This is a dns01 solver for FreeDNS.

Pull requests welcome. I'm completely unfamiliar with golang. I did it by looking at other webhook repos and this is the result.

Install

$ cd deploy
$ helm show values freedns-webhook > my-values.yaml
$ edit my-values.yaml
$ helm install -n cert-manager [INSTALLATION_NAME] freedns-webhook/ -f my-values.yaml

FreeDNS webhook settings

Normally if you haven't changed anything, the default namespace should be cert-manager. It should be within the same namespace for the webhook when you do helm install webhook -n cert-manager.

apiVersion: v1
kind: Secret
metadata:
  name: freedns-auth
  namespace: cert-manager
data:
  username: [YOUR_USERNAME_IN_BASE64]
  password: [YOUR_PASSWORD_IN_BASE64]
type: Opaque

Additionally, the following names can be customized

• acme.freedns.afraid.org
• freedns-auth
